I propose a fix in the branch "private-types" of my fork. This concerns universe polymorphism:
S1_rechnd Set Int (path_universe succ_int) base hast type Type(i) for some index i, but it can be evaluated to Int (of type Set). This case is rejected by a function "sort_cmp" in file kernel/reduction.ml ; I changed this function.

There's little to no chance we can get a reproducing test case out of this now, is there?
